Cervical spine positioning patterns amongst hand surgeons: A critical analysis of surgical posture.

AIM

This study aims to assess the cervical spine positioning of consultant and trainee hand surgeons during standardised hand surgeries, focusing on the prevalence of sustained end-range postures, particularly cervical spine flexion.

BACKGROUND

Surgeons often perform procedures that require maintenance of sustained postures for prolonged periods of time. Hand surgeons may be at increased risk of sustained end of range postures, particularly cervical spine flexion. This can lead to strain on the musculoskeletal structures of the neck. Recent evidence suggests a higher incidence of neck dysfunction in hand surgeons, leading to an associated morbidity.

METHODS

We examined hand surgeons of all experience levels during 40 common hand surgery procedures. We used real-time dynamic goniometric measurements of neck flexion using the "UPRIGHT GO 2" device and accompanying smartphone app. Neck flexion exceeding 40° was used as the threshold for defining an acceptable neck position.

RESULTS

Analysis included 20 total subjects at various levels of medical training (SHO n ​= ​6, Registrar n ​= ​9, Consultant n ​= ​5) performing surgeries under different conditions. Maladaptive neck positions were prevalent, with junior surgeons exhibiting such postures for 71 ​% of procedure time compared to 60 ​% for consultants. This underscores the potential contribution of sustained end-range postures to cervical spine dysfunction in hand surgeons, highlighting an early intervention opportunity. Notably, participants reported varied experiences with neck pain and expressed unanimous interest in integrating biofeedback posture devices into surgical training, with a single consultant expressing reservations.
